Wave Height Adjustment

A measurement that is added to the Base Flood Elevation (BFE) for V Zones shown on the Flood Insurance Rate Map (FIRM) published prior to 1981. For coastal communities, the BFE shown on FIRMs published prior to 1981 are stillwater elevations, which include only the effects of tide and storm surge and not the height of wind-generated waves.
